Water Heater Pressure Relief Valve Pipe

Tprs are designed to automatically release water in the event that pressure or temperature in the water tank exceeds safe levels.

Water heater pressure relief valve pipe. Temperature pressure relief or tpr valves are safety devices installed on water heating appliances such as boilers and domestic water supply heaters. 8 termination of the tpr drain pipe cannot be more than 6 inches or less than two pipe diameters above the floor ground or waster receptor flood rim level. This valve allows water or steam to escape from the water heater if the temperature or pressure gets. A good solution to this risk is the relief valve.

Step 2 hold the tpr valve with the slip joint pliers. Not be directly connected to the drainage system. If the water inside the unit gets too hot usually above 210 degrees or pressure builds up too high above 150 psi the water heater can become damaged or even explore. Not be smaller than the diameter of the outlet of the valve served and shall discharge full size to the air gap.

If pressure builds or temperatures reach dangerous levels the valve opens up and discharges the pressure. Discharge through an air gap located in the same room as the water heater. This prevents an explosion. Thread the tpr valve clockwise into the pressure relief fitting on the water heater and tighten it by hand until it is tight.

There are numerous possible reasons your water heater s pressure relief valve leaks. When the excessive pressure is built inside the hot water heater this temperature pressure relief valve helps in relieving pressure of the water. The former are generally limited to tankless water heaters and other equipment with built in overheat protection. The relief valve is an important safety feature on the water heater.

A typical water heater has a safety device known as a relief valve and is sometimes known as a temperature and pressure valve. Pressure relief valves used for hot water heaters and storage tanks can generally be divided into 2 main categories pressure only relief valves and t p temperature and pressure relief valves. Attached to the relief valve is a discharge pipe. A trapped tpr dischage pipe is a common defect when a replacement water heater s tpr valve is lower than the original one and the installer connects to the exisitng discharge piping at the wall.

The temperature pressure relief valve is basically attached with your hot water heater and controls or maintains pressure of the water. The discharge piping serving a pressure relief valve temperature relief valve or combination valve shall. Do you need a licensed plumber.
